BEIRUT (AP) -- Syrian opposition activists say rebel fighters have launched a new push to drive regime forces out of Syria's largest city, Aleppo.
Mohammed Saeed, an activist in Aleppo, says heavy clashes erupted Thursday in more than a dozen locations in the city, Syria's largest with 3 million people.
Speaking via Skype, Saeed also reported heavy shelling by government forces on several districts in the city.
Britain-based activist Rami Abdul-Rahman says rebels also attacked a compound of Syria's political security department in Aleppo.
Fighters trying to overthrow Syrian President Bashar Assad seized several neighborhoods of Aleppo two months ago, but neither side has been able to dislodge the other from their positions since.
